The ANTARES undersea neutrino telescope consists of a 3D grid of 900
photomultiplier tubes arranged in 12 strings, at a depth of 2475 m in the
Mediterranean Sea. After deployment of the first strings in 2006, half of the
detector is now fully operational and the complete detector is foreseen to
be finished in early 2008. Relic neutralinos produced after the Big Bang
are favoured...

Cosmic Rays and UHECR are reaching highest energy well above LHC ones.
Because photopion production they might hide UHE GZK neutrino that may airshower at
Earth Horizons. These Airshowers mostly are Tau induced ones. SUSY traces might be
also searched inside the same UHECR shower occuring on Earth. Indeed UHE neutralino
and other surprising SUSY secondaries may offer a novel Astronomy at...

We make an improved analysis on the flow of neutrinos originating from
WIMP annihilations inside the Sun and the Earth. We treat both
neutrino interaction and oscillation effects in a consistent
framework. Our numerical simulations are performed in an event based
setting, which is useful for both theoretical studies and for creating
neutrino telescope Monte Carlos. We find that the flow...

We found microwave reflection from a small rock salt samples irradiated by X-ray. The
reflection rate was consistent with number of ionized electrons by the irradiation.
Coherent reflection was indicated by time dependence of the reflection rate. It means
the irradiated size could be scaled up to ultra-high energy electromagnetic shower
using longer wavelength while the reflection rate is...

The discovery of a long-lived charged particle at future colliders can point towards
scenarios where the dark matter (DM) particle is superweakly interacting, and the
next-to-lightest particle (NLP) is charged and quasi-stable. Such a situation is
expected in several supersymmetric models, including gauge mediation and even minimal
supergravity, where the DM particle is the gravitino and...

The annihilations of WIMPs
produce high energy gamma-rays in the final state.
These high energy gamma-rays may be detected by IACTs
such as the H.E.S.S. array of Imaging Atmospheric Cherenkov telescopes.
Besides the popular targets such as the Galactic Center
or the galaxy cluster as M87, dwarf Sphreroidal galaxies
are privileged targets for searching a Dark Matter annihilation...
